        Phaseolus vulgaris Exerts an Inhibitory Effect on Platelet Aggregation through AKT Dependent Way

        Rosio Rodriguez-Azua,Eduardo Fuentes Quinteros,Alexandra Olate-Briones,Rodrigo Moore-Carrasco 한국식품영양과학회 2018 Preventive Nutrition and Food Science Vol.23 No.2

        The Phaseolus vulgaris (common bean), a worldwide vegetable of high consumption, can act as a nutritional supplement in the diet of oversized individuals to reduce weight. Studies have demonstrated the existence of molecules capable of inhibiting the breakdown of carbohydrates via inhibition of both α-amylases and glycosidases. Here, we describe a novel property of the Phaseolus vulgaris: inhibition of thrombotic cardiovascular events. Using assays to test platelet aggregation and secretion, and flow cytometry against the surface expression of P-Selectin. We show that bean extracts significantly reduced adenosine 5’-diphosphate and arachidonic acid induced-platelet aggregation. The mechanism underlying such effect appears to be mediated by AKT, since AKT hypo-phosphorylation decreases the “inside out” activation of platelets. In sum, our results support the hypothesis that common beans are nutritional ingredients that help reduce the risk of cardiovascular diseases associated with platelet hyper-reactivity.

        Factors Associated with Prolonged Patient-Attributable Delay in the Diagnosis of Colorectal Cancer

        Irene Zarcos-Pedrinaci,Teresa Téllez,Francisco Rivas-Ruiz,María del Carmen Padilla-Ruiz,Julia Alcaide,Antonio Rueda,María Luisa Baré,María Manuela Morales Suárez-Varela,Eduardo Briones,Cristina Sarasq 대한암학회 2018 Cancer Research and Treatment Vol.50 No.4

        Purpose The delayed diagnosis of colorectal cancer (CRC) may be attributable to sociodemographic characteristics, to aspects of tumour histopathology or to the functioning of the health system. We seek to determine which of these factors most influences prolonged patient-attributable delay (PPAD) in the diagnosis and treatment of CRC. Materials and Methods A prospective, multicentre observational study was conducted in 22 Spanish hospitals. In total, 1,785 patients were recruited to the study between 2010 and 2012 and underwent elective or urgent surgery. PPAD is considered to occur when the time elapsed between a patient presenting the symptom and him/her seeking attention from the primary care physician or hospital emergency department exceeds 180 days. A bivariate analysis was performed to assess differences in variables segmented by tumour location and patient delay. Multivariate logistic regression analysis was performed on the outcome variable, PPAD. Results The rate of PPAD among this population was 12.1%. PPAD was significantly associated with altered bowel rhythm (odds ratio [OR], 1.36; 95% confidence interval [CI], 1.02 to 1.83) and with adenocarcinoma histology, in comparison with mucinous adenocarcinoma (OR, 2.03; 95% CI, 1.11 to 3.71). Other sociocultural factors and clinicopathological features were not independent predictors of PPAD. Conclusion Many patients do not consider altered bowel rhythm an alarming symptom, warranting a visit to the doctor. PPAD could be reduced by improving health education, raising awareness of CRC-related symptoms.
